DEM/DTM CONTOUR MAPPING
We create DEM/DTM and contour maps to equip urban planners with landscape details. Such in-depth spatial information can help in slope pattern and watershed analysis, buffer zone generation etc. DEM/DTM and contour maps are necessary for the formulation of engineering solutions and are indispensable for efficient urban development.
Digital Elevation Model (DEM)
We use advanced tools to create Digital Elevation Models (DEM) that provide an in-depth analysis of the land for urban planning and management. We create DEM from high-resolution satellite imagery using digital photogrammetry technology. DEMs are useful frameworks on which networks for sewerage and drainage, solid waste movement, roads, telecommunication, optical fiber etc. can be mapped. These can also be used for transportation and infrastructure planning, flood management etc.
Digital Terrain Model (DTM)
A Digital Terrain Model (DTM) adds further layers like terrain information, elevation of man-made structures etc. to enhance the Digital Elevation Model (DEM). It comprises regularly spaced points representing distinct terrain features of the bare earth. We generate detailed and accurate DTMs of the areas of interest for contour generation, land use mapping etc. These DTMs have application areas in planning road networks, efficient traffic management, drainage, sewerage network and railway network planning and management of other features.
We generate accurate contour maps using methods like image processing, topographical survey, contour vectorization, labeling and editing. These contour maps form the necessary frameworks for various engineering projects that require slope analysis, generation of layout planning maps etc.
